PhD proposal: Privacy protection against inference attacks in social networks

Title: Privacy protection against inference attacks in social networks

Location: LORIA /INRIA — Nancy, France

Project-team: PESTO

Scientific Context: The majority of social networks (like Facebook, LinkedIn, etc) provide control functions to limit the visibility of certain data (such as friend list, wall posts and images) to a specific user group. However, most of users are unaware of the risks associated with the publication and exchange of personal data on social networks. For example, publishing and sharing location information on Facebook could easily lead to a burglary. Privacy risks may arise from explicit and/or implicit information that we can learn from online data. These risks due to data sharing are constantly increasing, allowing privacy attacks with unfortunate consequences. Therefore  it is imperative to devise tools that allow users to control themselves the usage that their data can be destined to. These tools assist users to detect and minimize the dissemination of personal information.

– Missions: The PhD student is expected to contribute to the design, analysis and development of an original solution for protecting privacy in social networks. By combining recent advances in machine learning and algorithmic, the objective is to prevent sensitive information dissemination.

More information is available on request.

Key words: Social networks, Privacy, Anonymization, Link prediction, Inference attack, Machine learning
